  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • How conditions affect cookies and air pollution control solutions

    Chocolate chip cookies are one of my favorite treats. Butter, sugar, eggs, flour, vanilla, and, of course, chocolate chips. Combine the ingredients together and you get a delicious cookie. Somehow, using the same ingredients the cookies do not always turn out the same. Sometimes they are thinner and crispier. Other times, they are soft and chewy. After watching cooking shows, I have come to ...

  • Exergy analysis of process heaters

    A thermodynamic analysis is proposed to investigate the entropy generation in process heaters. It is found that the major portion of the exergy losses occur in the stack. It is also found that the excess air decreases the first law efficiency while the second law efficiency remains nearly constant. Although the first law efficiency is found to be of the order of 70-90%, the second law efficiency ...

  • Headspace gas analysis video

    Why does headspace gas need to be measured? To check the continuity and quality of the gas supply to the packing machine, the efficiency of the flush/vacuum cycle and the integrity of the pack seal. To optimise gas usage and save costs. To meet customer headspace gas quality standards. ...

  • CFD Analysis of Gas Cooling

    In many industrial processes, hot gas is cooled down due to the evaporation (boiling) of sprayed droplets. The effects of two different atomizer types, inner mixing air atomizing nozzles and flow back nozzles, on the cooling behavior inside a spray tower for a typical flue gas are discussed. The heat and mass transfer is computed using computational fluid dynamics (CFD). The interaction between ...

  • Sensitivity analysis in a simulated auto thermal Natural Gas reforming process

    Auto Thermal natural gas Reforming (ATR) is one of the mostly used conventional hydrogen generation technologies by the highly developed countries. ATR reactors do not need any direct or indirect heat exchanger, and that is why they are more compact and so preferable than the other reformers. In this study, a process including reformers, carbon dioxide sequestration and a cryogenic separation ...

  • The analysis of carbon dioxide in natural gas

    Abstract The composition of natural gas varies but consists mainly of methane and varying amounts of heavier aliphatic hydrocarbons, nitrogen and carbon dioxide ...

  • Production of synthetic gasoline and diesel fuels by alternative processes using natural gas, coal and biomass: process simulation and economic analysis

    The problem of producing synthetic liquid fuels by alternative routes is addressed. Industrial processes known as Gas To Liquid (GTL), Coal To Liquid (CTL) and Biomass To Liquid (BTL) are considered: they use natural gas, coal and biomass as feedstocks, respectively. By means of process simulation, it is shown that the fuel produced on a weight basis per unit of feedstock (natural gas, coal and ...

  • Comparison and analysis of the expansion process in a CO2 transcritical cycle

    The isentropic and isenthalpic expansion processes in a CO2 transcritical cycle were analysed thermodynamically. It was found that the effective refrigeration capacity of the cycle with the isentropic expansion process is higher than the cycle with the isenthalpic expansion process. The increment is slightly larger than the expansion work recovered because of the transcritical nature of the ...

  • Gas cell selection for analysis of electronic gases

    APIMS and FTIR remain the preferred analytical tools for monitoring impurities in the electronic  specialty gases used by the semiconductor industry, although other tools such as CRDS are currently finding application in selected cases. FTIR spectroscopy offers the advantage of the simultaneous measurement of all gaseous species that exhibit dipole moment changes during vibrations at ...

  • Leak detection in semiconductor fab gas processes

    Problem Statement Often times in semiconductor fabs moisture levels are monitored to ensure that products aren’t damaged by excess moisture in the process. If there are above normal levels of moisture, pinpointing the source of that moisture can be difficult. The moisture could be evolving from impurities in gas tanks or leaks in the sampling lines. One way to avoid downtime ...

  • Total solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • FTIR gas analysis improves container safety

    Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...
